I was out on a bus run til 4:10pm so that's 9:10pm there. Having slept poorly last night and had a poor midday nap I hope my non attendance can be excused.
Right now I'm back to ludicrous work hours. Those are really cutting into what I do with coding and electronics. I might get some time next week as I have time booked off work. Last week was a bit stressful as I had a big tyre explode as I was driving on Thursday. Big is 295/75R22.5 (22.5 inches) and pressurised to 100psi. There are still bits of that tyre lying in the road where it exploded.

I have several current projects. They're all based around the ATTTiny13, ATTiny44 and ATTiny85 microcontrollers. 

I'm rebuilding the Morse flasher for the 20 foot LED phallus. It had been working well from a Raspberry Pi Pico and a relay board but the humidity got to the solderless breadboard. That had be redesign it to run off an ATTiny13 with a shorter message. I wrote a program in Python to generate the C++ code for the ATTiny13 since there's only 1K available on the ATTiny13 for code and only 256 bytes for variables. 

Time is the biggest challenge right now.
One of my other plans is a simple set of traffic lights run off an ATTiny13, a shift register and darlington transistor chip, powered by a 3 volt 2032 battery.
